FAQ

Frequently asked questions

What does this website visitor identification tool show?

Enter a domain and the tool matches 5 buyers to that site, with names, titles, LinkedIn, emails, and a lead score. It is a sample, not the full product. Knock2 identifies 62% of US engaged sessions at the person level and 93% of engaged sessions at the account level. Plans start at $199 a month, with a 7-day free trial.

How does Knock2 identify visitors on my site?

You add a small script to your site. When someone visits, Knock2 matches that visit against licensed identity data to resolve the person and the company behind it. You get name, title and business contact details.

IP address alone resolves a corporate network, not a visitor on home WiFi, mobile or a VPN. Knock2 also uses device-level signals for more precise matching.

What's the difference between account-level and person-level identification?

Account-level identification tells you which company a visitor is from. It's useful for account-based marketing, territory routing, and understanding which target accounts are actively researching you. Person-level identification tells you exactly who the individual is: name, title, work email, phone, and LinkedIn profile. Person-level data is only available for US traffic due to privacy regulations in other regions.

Will this work with my CRM and sales tools?

Yes. Native integrations are built for HubSpot, Salesforce, Slack, Apollo, Outreach, Lemlist, Instantly, and Clay. For anything not on that list, webhooks cover Zapier, Make, n8n, and any other tool that accepts them. Identified visitors can be routed in real time based on lead score, pages visited, firmographics, persona match, UTMs, or any combination.

Is this actually legal? How does Knock2 identify people without them opting in?

Yes. Knock2 is built on the same class of identity and analytics technology already running on most B2B websites.

Person-level identification runs on US traffic only, by design. Everywhere else, Knock2 returns company-level information only. That is how it stays within GDPR, CCPA and ePrivacy expectations. The identity data itself is licensed from established data providers.

Does Knock2 work outside the US? What about GDPR?

Person-level identification, with names, emails and contact details, is limited to US traffic by design. Account-level identification works globally. This is how Knock2 stays compliant with GDPR, CCPA and the ePrivacy Directive in Europe. You won't see individual European or Asian visitors' personal details, but you will see which companies are visiting.

How does pricing work?

Plans start at $199/month (Startup) and scale with included credits. Identifying an account costs 1 credit, identifying a person costs 6 credits, and prospecting additional contacts at an account costs 2 credits. Every plan includes a 7-day free trial.

Is Knock2 the same company as Knock AI?

No. Knock2 is knock2.ai, website visitor identification for B2B teams. Knock AI at knock-ai.com is a different company. Check the domain before comparing match rates or pricing.
